What is the best web-browser plug-in for downloading videos from YouTube and other video sharing web-sites?
I tried
Fast Video Download plug-in (extension) for Firefox. It is great, but it supports only youtube.com, break.com, dailymotion.com, hi5.com, metacafe.com, vids.myspace.com, video.google.com and several other web-sites that I don't use. Well actually this list covers 95% of my downloading needs, but still I would like something more universal.
I'm Ok with many browsers. I just need the best plug-in, whether it is an extension for Firefox, a widget for Opera, a plug-in for Internet Explorer.
Thank you very much in advance.
